We are always so positive here, talking about the things we like best. I thought it might be fun to be negative and talk about what we hate in classical music (not just piano music, because there is more that that). It is my philosophy that for each thing you truly love, there must be some other thing you truly hate. Yin and Yang, so to speak
It's just not possible IMO to love/like all
music, and I question the musical taste of anybody who says they do.
So I've listed my top ten of pet hates in no particular order.
Virtuoso violin music a la Paganini and Sarasate, with lots of sixths, octave doublings, and sul ponticello passages
Transcriptions for strange combinations of instruments, like recorder or saxophone quartet
Schubert works for male choir
Orchestrations of piano pieces (Ravel in particular)
Flute and harp music
Mendelssohn string quartets
Fortepiano and other instruments that fill the gap between harpsichord and piano
Vivaldi (most of it)
Operetta (most of it)
Let me take a little dig here, so do not think I am either serious or miffed!
Recorders... Well, there was a time when there were really recorder ensembles, but I agree: Mozart played by for recorders...
Talking of Mozart, he was not partial to the flute either!
All right, Ravel orchestrated by Kostellanetz (is that spelled right?) is one thing, but Musorgsky orchestrated by Ravel?
Operetta… but do you know Giuditta?
To the peril of my life I will make my list and it starts, as you might have guessed, with
1. Liszt (Consolations and Liebestraume excepted)
2. Chopin solo piano music (but have you ever heard his songs, his piano trio, his Krakowiak rondo?)
3. The Art of the Fugue, a good part of the Well-Tempered and most of the Musical Offering (trio-sonata excepted)
4. Italian opera, Verdi first (the Harold Robbins of opera)
5. Italian tenors a la Pavarotti (even if they are not always Italian. You know what I mean)
6. Virtuoso music that sounds like virtuoso music (Oh, ah… He can play the violin with his teeth!)
7. Mozart Symphonies (except the 4 last ones)
8. Most of Schoenberg (tonal, atonal and 12-tone: it is all the same to me) and his acolytes (the Gurrelieder are saved)
9. Ee-aw music
10. Tchaikovsky's concerti, tone poems and late symphonies (numbered and not)
